Proposals for amendments to Regulations Nos. 4, 6, 7, 19, 23, 38, 48, 50, 77, 87, 91, 98, 112, 113, 119, 123 to clarify requirements for light sources in lighting and light-signalling Regulations listed in Annex 4 to UN Regulation No. 0. The proposed UN R0 on whole vehicle type approval requires submission of approval certificates for components and systems. Vehicle manufacturers work directly with UN R48 approvals, but lamp and device approvals are generally handled by lighting suppliers. UN R48 includes provisions for listing approvals of lighting units, but not for approvals of light sources (presently UN R37, R99, and R128). This set of proposed amendments introduces provisions for light-source approvals under the device regulations.

Proposal to

1. reference the compliance requirements for installation contained in Regulations Nos. 48, 53, 72 and 86
2. complete the deletion of distributed lighting systems (light generators),
3. clarify the definition of “type”, with regard to manufacturer, trade names and marks,
4. to introduce editorial improvements to the requirements for markings,
5. amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45,
6. clarifies the heat test cycle,
7. and harmonizes requirements across Regulations Nos. 19, 98, 112, 113 and 123

This proposal consolidates UN R19 prior to its being frozen and superseded by the three new comprehensive regulations (forward lighting, light-signalling, and retro-reflective devices) developed under the Simplification of Lighting Regulations program.
